Answer: x = 5
Step-by-step explanation:
Hey there! If you have any questions, feel free to let me know in the comments.
Step 1: Simplify 20 - 4x - 15 - 4x to 5 - 8x.
5 - 8x = -6x - 45 + 8x
Step 2: Simplify -6x - 45 + 8x to 2x - 45.
5 - 8x = 2x-44
Step 3: Add 8x to both sides.
5 = 2x - 45 + 8x
Step 4: Simplify 2x - 45 + 8x to 10x - 45.
5 = 10x - 45
Step 5: Add 45 to both sides.
5 + 45 = 10x
Step 6: Simplify 5 + 45 to 50.
50 = 10x
Step 7: Divide both sides by 10.
50/10 = 10x/10
Step 8: Simplify 50/10 to 5.
x = 5
Answer:
Step-by-step explanation:
Here you go mate
step 1
20-4x-15-4x=-6x-45+8x equation
step 2
20-4x-15-4x=-6x-45+8x simplify for x
20+(-4x)+(-15)+(-4x)=(-6x)+(-45)+8x
step 3
(-4x+-4x)+(20+(-15)=(-6x+8x)+(-45) add brackets to seperate the equations
step 4
-8x+5=2x+-45 combine the terms that are alike
step 5
-8x+5(-2x)=2x-45(-2x) subtract -2x(the ones in the brackets)
-10x+5=-45
step 6
−10x+5(-5)=−45(-5) subtract -5
-10x=-50
step 7
-10x/-10=-50/-10 divide by -10
step 8
50/10 Divide
Answer
x=5
