Take the coefficient of x (22) divide it by 2, square it, than add it to both sides of the equation.
22 / 2 = 11 and 11 * 11 = 121
3/4-4z+5/4z-1/2+1/2z
(simplify fractions by taking away)3/4-1/2=1/4
(simplify again but only fraction with a denominator of z)5/4z+1/2z=7/4z
so its 1/4+7/4z-4z
OR
I don't know if you're supposed to change by taking away 4z which is the same as 1/4z.
if so then
7/4z(previous calculation but you can use the beggining fractions if you want just add all 3 fractions with z as a denominator)-1/4z=6/4z
so its 1/4+6/4z
I don't know the others sorry
Answer:
B
Step-by-step explanation:
We devide the equation by 20
15x/20=20/20
x=3/4
So slope intercept form is y=mx+b to convert this equation into slope intercept form we must make everything equal to y
3x-2y=7
3x=7+2y we add 2y to move it to the other side
3x-7=2y We subtract seven to have 1y by itself and then divide by two to get it into simplified slope intercept form
Answers=
3/2x-3.5=y or written as=
y=3/2x-3.5
