Hey there! :)

3t - 18 = 4(-3 - 43t)

Let's start on the right side of the equal sign by multiplying "4" with everything inside of the parenthesis. Keep in mind that a negative times a negative is a positive & a negative times a positive is a negative.

  • 4 × -3 = -12
  • 4 × -43t = -172t

Let's put this all together:

3t - 18 = -12 - 172t

Now, we need to isolate "t." We can do this by adding 18 to both sides along with adding "172t" to both sides.

3t - 18 + 18 + 172t = -12 - 172t + 172t + 18

Simplify.

3t + 172t = -12 + 18

Simplify - add like terms!

  • 3t + 172t = 175t
  • -12 + 18 = 6

Let's put this all together:

175t = 6

Divide both sides by 175.

175t ÷ 175 = 6 ÷ 175

Simplify.

t = 6/175

Hope this helped! :)

Step 1

3t−18=4(−3− 43 t)   Equation/Question

Step 2

3t-18=4(−3− 43 t)   Remove parenthesis

3t-18=-172t-12

Step 3

3t-18=-172t-12  Add 172t

175t-18=-12

Step 4

175t-18=-12   Add 18 to sides

175t=6

Step 5

175t=6   Divide sides by 175

[tex]\frac{175t}{175} =\frac{6}{175}[/tex]

answer

t=[tex]\frac{6}{175}[/tex]

Hope this helps
