/what is the solution for x in the equation 10x - 4.5 + 3x = 12x - 1.1
2 answers:
Answer:
x = 3.4
Step-by-step explanation:
Step 1: Write equation
10x - 4.5 + 3x = 12x - 1.1
Step 2: Solve for <em>x</em>
Combine like terms: 13x - 4.5 = 12x - 1.1 Subtract 12x on both sides: x - 4.5 = -1.1 Add 4.5 on both sides: x = 3.4
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
10(3.4) - 4.5 + 3(3.4) = 12(3.4) - 1.1
34 - 4.5 + 10.2 = 40.8 - 1.1
29.5 + 10.2 = 39.7
39.7 = 39.7
Answer:
13x - 12x = - 1.1 + 4.5
Step-by-step explanation:
x= 3.4
