The current average is: (25+45+50+36)/4
=39
Lara wants to increase her average by 4
So her average should be 43.

(25+45+50+36+x)/5=43
(156+x)/5=43
156+x=215
x=59

Lara has to score 59 in her next test to increase her average by 4

can someone help me!! Use algebraic rules of equations to predict the solution type to the system of equations. Include all of y
xz_007 [3.2K]

Answer:

x + y = 4 Equation 1

y = 2x -1 Equation 2

-2x + y = -1

x + y = 4

Subtract

You will get

- 3x = -5

Divide by -3

-3x / -3 = - 5 /-3

x = 5/3

Substitute x into equation 1

x + y = 4

x = 5/3

5/3 + y = 4

y = 4 - 5/3

y = 7/3

x = 5/3 y = 7/3

Hope this helps.
