Answer:

x = 7

Step-by-step explanation:

9x - 3 = 60

Add 3 to both sides: 9x (- 3 +3) = (60+3)

9x = 63

Divide each side by 9: (9/9)x = (63/9)

x = 7

What’s the answer cause I need it bad

pentagon [3]

Answer: $(-9,-3)$

Step-by-step explanation:

Given the following system of equations:

$\left \{ {{2x=-78-20y} \atop {-x=-51-20y}} \right.$

In order to solve the System of equations, you can use the Substitution method. The steps are:

1. You can solve for "x" from the second equation:

$-x=-51-20y\\\\x=51+20y$

2. Substitute the equation obtained into the first original equation:

$2x=-78-20y\\\\2(51+20y)=-78-20y$

3. Now you must solve for "y":

$102+40y=-78-20y\\\\40y+20y=-78-102\\\\60y=-180\\\\y=\frac{-180}{60}\\\\y=-3$

4. Substitute the value of "y" into the equation $x=51+20y$ and evaluate:

$x=51+20(-3)\\\\x=51-60\\\\x=-9$

Then, the solution is:

$(-9,-3)$

Find the y- intercept and x-intercept of the line. <br><br> 4x-y=8

Darya [45]

Answer:

x-intercept is (2,0)

y-intercept is (0,-8)

Step-by-step explanation:

to find the 'x-intercept', substitute zero for 'y' and solve:

4x - 0 = 8

4x = 8

x = 2; x-intercept is (2,0)

4(0) - y = 8

0 - y = 8

y = -8; y-intercept is (0,-8)
