Answer:
x/3 -3= 18 (add three to both sides)
x/3= 21
x/3(*3) =21(*3) (multiply by 3 on each side to cancel out the division)
x= 63
63/3-3=18
21-3=18
18= 18 (checking answers)
Step-by-step explanation:
Answer:
x=-5
Step-by-step explanation:
4(x-5)+2=x+3 As the first step says, distribute the 4 (multiply all numbers in the parentheses by 4).
4x-20+2=x-3 Combine like terms. For example, the -20 and 2 are like terms because they are both their own numbers and not attached to a variable.
4x-18=x-3 Subtract x from each side. Now, we can get x to only one side.
<u>-x -x</u>
3x-18=-3 Add 18 to both sides.
<u>+18 +18</u>
3x=-15 Divide both sides by 3.
<u>/3 /3</u>
x=-5
I hope this helped you!! Have a great day c:
Answer: No solution
Step-by-step explanation:
7(x+4) - 6(x+3) = x + 5
7x + 28 - 6x - 18 = x + 5 distributing
7x - 6x - x = -28 + 18 +5
0 = -5 <u>Not true</u>
No solution
