Use the method of elimination to solve the following pairs of simultaneous equation 8y+4z=7 6y-8z=41
5A-2B=14 2A+2B=14 ADD BOTH EQUATION TOGETHER 5A-2B=14+2A+2B=14/7A=28 7A=28 DIVIDE BOTH SIDE BY 7. 7A/7 28/7 A=4
use the method of elimination and substitution to solve 5a-2b=14 and 2a+2b=14
B=4;a=5
X varies directly at y and x=3 when y=12 find y when x=4
5A-2B=14 2A+2B=14
I need solution of 2a+2b=14
PLEASE I NEED A ANSWER FOR THIS
give me d answer
just what I wanted to ask for
