Step-by-step explanation:

One thing that will be very useful in solving these problems is the distributive property, that states .

(1) Use the distributive property to open the parentheses, getting:

Then, combine like terms and isolate on one side to get:

Divide both sides by -9 to get:

(2) Combine like terms and isolate on one side to get:

Divide both sides by -8 to get:

(3) Use the distributive property to open the parentheses, getting:

Combine like terms and isolate on one side to get:

Divide both sides by 21 to get:

(4) Use the distributive property to open the parentheses, getting:

Combine like terms and isolate on one side to get:

Divide both sides by -11 to get:

(5) Combine like terms and isolate on one side to get:

Divide both sides by -4 to get:

(6) Combine like terms and isolate on one side to get:

Divide both sides by -8 to get:

(7) Use the distributive property to open the parentheses, getting:

Combine like terms and isolate on one side to get:

Divide both sides by -10 to get:

(8) Use the distributive property to open the parentheses, getting:

Combine like terms and isolate on one side to get:

Divide both sides by 15 to get:

(9) Simplify the left side of the equation to get:

Add 3 to both sides to arrive at:

(10) Use the distributive property to open the parentheses, getting:

Combine like terms and isolate on one side to get:

Divide both sides by 6 to get:

Hope this helps :)

P.S. These problems took 1 hour for me to solve and type the solutions. Please give Brainliest if this answer helped you :)

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
