Can someone please help me​
Sonja [21]

Answer:

(7,9)

Step-by-step explanation:

7x - 8y = -23

7x - 7y = -14

Solve the equation for 7x

7x - 8y = -23

7x = -14 + 7y

Substitute the given value of 7x into the equation 7x - 8y = -23

-14 + 7y - 8y = -23

solve the equation for y

y = 9

substitute the given value of y into the equation 7x = -14 + 7y

7x = -14 + 7(9)

solve the equation for x

x = 7

<u>(7,9)</u>

Point F lies between points G and M. GF What is the value of x? 10x +4, FM = 20, and GM = 13x​
egoroff_w [7]

The value of x is 8.

<h3>How to find the value of x?</h3>

Equations are written as two expressions joined by an equal sign. The terms on either side of the equal sign are called the "left side" and "right side" of the expression. It is often assumed that the right side of the equation is zero.

given that Point F lies between points G and M.

GF = 10x +4, FM = 20,GM = 13x.

so now GM = GF + FM

3x =( 10x + 4) + 20

13x = 10x + 24

13x - 10x = 24

3x = 24

x = 24/3

x = 8

so, the value of x is 8.

now check if it is wrong or correct

13(8) = 10(8) + 4 + 24

104 = 80 + 28

104 = 104
