Question

If x = 4, what is the y value for the following equation?

y = 12x + 6 - 2x + 2

y = 10
y = 12
y = 48
y = 52

Answer 1

y = 48

Explanation:

1. Substitute 4 in place of x in the equation
2. The equation should be y = 12 (4) + 6 - 2 (4) + 2
3. Following the order of operations, multiple 12 x 4 and -2 x 4
4. 12 x 4 = 48 and -2 x 4 = 8
5. Rewrite the equation again to y = 48 + 6 - 8 + 2
6. When we solve the equation, y = 48

Answer 2

Y=12(4)+6-2(4)+2
Y=48+6-8+2
Y=48
