Question

Find the solution
y=5x-13
4x+3y+18

Answer 1

is this in a square

Answer 2

y=5x-13
4x+3y+18

Since it is a given that y=5x-13 a method that would be more suitable to use here would be substitution
Are you familiar with that?

Answer 3

@tanijah12 what method you know to solve a system of equation ?

Answer 4

it says Solve the system of equation using substiion

Answer 5

substitution ? ok so do you know what mean this ?

Answer 6

no

Answer 7

ok

so this mean that how is the first equation that y=5x-13 so this expression of y you need substitute in place of y inside second equation - do you can make it ?

Answer 8

please you cooperate that i like help you

Answer 9

how will be than ?

Answer 10

just substitute the 5x-13 in place of y inside second equation - ok. ?

Answer 11

sorry i need to go but i will come back little later

Answer 12

ok

Answer 13

\[\huge~\rm~\bf~4x+3(5x-13)+18 \]
solve for x

Answer 14

@tanijah12 now i see that the second equation is 4x+3y= 18 not + 18

right ?
