Question

Please fix these problems I will give a star. Questions down below

Answer 1

In the first one you can use substitution

Answer 2

2x-3y = 26

2x-3(5x) = 26 ... replace y with 5x (works because y = 5x is given as the first equation)

2x-15x = 26

-13x = 26

x = ??

Answer 3

-2

Answer 4

yes

Answer 5

now plug that into any equation with x & y in it, then solve for y

the easiest is y = 5x

Answer 6

-2y/-2 =-5/-2=2?

Answer 7

for -5 i mean 5

Answer 8

what do you mean?

Answer 9

oh wait, I messed up. hold on

Answer 10

1)substitute x= -2 in y=5x
y= 5*(-2)
y= -10

Answer 11

2) 2x +5y=14 -----I
x-3y=4-----------II


multiply equation II with 2 and sutract from eq I
you will get ,y=6/11

Answer 12

substitute y= 6/11,in equation II
x-3*6/11=4
x-18/11=4
x= 4+18/11
x= (44+18)/11
x= 62/11

Answer 13

are u there

Answer 14

I need help with the third problem
