Question

Enter the value x that makes the equation 7x-4+8x-3=-67

X=

Answer 1

x = -4

Step-by-step explanation:

1. Collect the like the terms: 15x - 4 - 3 = -67
2. Calculate the difference: 15x -7 = -67
3. Move constant to the right side and change its sign: 15x = -67 +7
4. Calculate the sum: 15x = -60
5. Divide both sides of the equation by 15: x = -4

Answer 2

7x-4+8x-3x=-67

Combine the x’s

12x-4=-67

Bring the -4 under the -67 and make it positive

Add the 4 and -67

12x=-63

Put division signs under bothering numbers and divide by 12. The 12x/12 would cancel out to be x.

Divide -67/12

X=-5.25
