1. You need to make a proportion
2. Your proportion would be 8 over 10 equals X over 15
3. Your equation would be 10x=15(8)
4. 15x8=125
5. 10x=125
6. you would divide 125 by 10
7. thats your answer
Answer:
x=11.7
Step-by-step explanation:
When every you have a straight line with a transversal, the line going through the straight line, the two angles will add up to 180.
180=10x+2+5x+3 ---> combine like terms
180=15x+5 ---> subtract 5 to the other side
175=15x ---> divide 15 to the other side
x=11.7
Answer:
x= -1
Step-by-step explanation:
4x+3=x
we subtract x to both sides of the equation:
4x -x +3 = x-x
we have:
3x +3 = 0
we subtract 3 to both sides of the equation:
3x +3 -3 = -3
3x = -3
we divide by 3 both sides of the equation
3x/3 = -3/3
x= -1
we test the result in the original equation:
4x+3=x
4*(-1) + 3 = -1
-4 +3 = -1
-1 = -1
so finally x= -1
