Question

Solve for x.

2x + 4x + 3 = 7 – x + 10

a: x = −4
b: x = −2
c: x = 2
d: x = 4

Answer 1

Answer:

A.) 2(-4) + 4(-4) + 3 = 7 -(-4) + 10

-8 -16 + 3 = 21

-24 + 3 = 21

-21 = 21

Answer= -1.

B.) 2(-2) + 4(-2) + 3= 7 -(-2) + 10

-4 -8 + 3 = 19

-12 + 3 = 19

-9 = 19

-2.1.

C.) 2(2) + 4(2) + 3 = 7 -(2) + 10

4 + 8 + 3 = 7 -2 + 10

15 = 15

1.

D.) 2(4) + 4(4) + 3 = 7 -(4) + 10

8 +16 + 3 = 7 -4 + 10

27 = 13

0.481.
