Answer:
5 x plus 50 I think but you ate right about it
Answer:
y=-3 x=4
Step-by-step explanation:
y=3x+3
y=3x+3 y=x-1
+<u>1</u><u> </u><u> </u><u> </u><u> </u><u>+</u><u>1</u>
y+1=x
y=3(y+1)+3
y=3y+3+3
y=3y+6
<u>-3y=-</u><u>3y</u>
-2y=6
-y=3
<u>y=</u><u>-</u><u>3</u>
3=x-1
<u>+1=+1</u>
<u>4</u><u>=</u><u>x</u>
Answer:
x = 9
Step-by-step explanation:
Each angle equals 60 since it is an equilateral triangle
7x-3 = 60
add 3
7x = 63
divide by seven on both sides
x = 9
I hope this helps!!
2(5x+7)+8x-7=27
We move all terms to the left:
2(5x+7)+8x-7-(27)=0
We add all the numbers together, and all the variables
8x+2(5x+7)-34=0
We multiply parentheses
8x+10x+14-34=0
We add all the numbers together, and all the variables
18x-20=0
We move all terms containing x to the left, all other terms to the right
18x=20
x=20/18
x=1+1/9
