Y=-5x+30 7x+3y=42 1111

Step-by-step explanation:

7x+3y=42.

y=-5x+30.

7x+3(-5x+30)=42

7x-15x+90=42

8x=42-90

-8x=-48

x=-48/-8

x=6

y=-5x+30

y=-5×6+30

=-30+30

y=0

(6,0)

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
