Answer:
-0.5 is not a solution
2 is a solution
Step-by-step explanation:
To check if something is a solution of the equation, you need to substitute the value in place of the variable
15 + 2y = -12 - 4y
15 + 2(-0.5) = -12 - 4(-0.5)
15 - 1 = -12 + 2
14 ≠ -10 ∴ -0.5 is not a solution
5 - 2(3x + 5) = 3 - 10x
5 - 2[3(2) + 5] = 3 - 10(2)
5 - 2(6 + 5) = 3 - 10(2)
5 - 12 - 10 = 3 - 120
-17 = -17 ∴ 2 is a solution
Answer:
81
Step-by-step explanation:
325-120=205
205/2.53=81

Answer:
Step-by-step explanation:
<u>Solve for x:</u>
- 1/2 (4x - 8) + 3x = 36
- 2x - 4 + 3x = 36
- 5x - 4 = 36
- 5x = 40
- x = 40/5
- x = 8
