Decide whether the two equations are equivalent.

2a + 6 = 12

a+3 = 6

Yes

Step-by-step explanation:

2a+6=12

2a=12-6

2a=6

a=6/2

a=3

a+3=6

a=6-3

a=3

Yes, the two equations are equivalent.

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
