An addition sign between 978 and 842 would make the equation true!
Answer:
x=7
Step-by-step explanation:
Simplifying
3x + 2(4 + 6x) = 113
3x + (4 * 2 + 6x * 2) = 113
3x + (8 + 12x) = 113
Reorder the terms:
8 + 3x + 12x = 113
Combine like terms: 3x + 12x = 15x
8 + 15x = 113
Solving
8 + 15x = 113
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + 15x = 113 + -8
Combine like terms: 8 + -8 = 0
0 + 15x = 113 + -8
15x = 113 + -8
Combine like terms: 113 + -8 = 105
15x = 105
Divide each side by '15'.
x = 7
Simplifying
x = 7

Answer:
x < 3
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
4*x-7-(5)<0
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
4x - 12 = 4 • (x - 3)
Equation at the end of step 1 :
Step 2 :
2.1 Divide both sides by 4
Solve Basic Inequality :
2.2 Add 3 to both sides
x < 3
Here you go, hope it helps!
