-12x = 12x
Start by moving all the terms with the variable you want to solve for on one side of the equation and the rest on the other side of the equation.
We will move 12x to the left side of the equation by subtracting 12x from both sides. Now your equation should look like:
-24x = 0
Isolate the variable x by dividing both sides by -24. Everything divided by 0 is equal to 0, so that means x will be equal to 0.
x = 0
Your answer is x = 0.
Answer:
False
Step-by-step explanation:
y=5x + 5
0=5 (5)+5
0=10+5
0≠15
False
Answer:
y = m x + b equation of a straight line
m m' = -1 condition for perpendicular lines
If y = 4 x - 7 then m = 4 so m' = -.25
Y = -.25 X + A we need to find A
A = Y + .25 * 8 = 2 + 2 = 4
Y = -.25 X + 4
Check:
2 = -.25 * 8 + 4 = -2 + 4 = 2
Answer:
I think Substitution
Step-by-step explanation:
Because x is already solved for in the second equation.
