Answer:

x = 3/2 or 1.5

Step-by-step explanation:

y = 3 in the equation 2x + 3y = 12

Substitute 3 in for y.

2x + 3(3) = 12

Multiply.

2x + 9 = 12

Subtract 9 from both sides.

2x + 9 - 9 = 12 - 9

2x = 3

Divide both sides by 2.

2x ÷ 2 = x

3 ÷ 2 = 3/2 or 1.5

x = 1.5

Answer:

X = 1.5

Step-by-step explanation:

So we know that Y = 3 and 3 x 3 = 9, then we need to get the difference of 9 to 12

12 - 9 = 3

we now know that x will equal 3, so 2 x 1.5 = 3, and 3 + 9 = 12

(Full equation)

2 x 1.5 + 3 x 3 = 12
