Transcribed Image Text:Solve the following systems by the equalization method. IN DIGITAL FORMAT c) 3x+4y=24 -x+y=-1] d) 4x+5y-24 2x-2y=-6
Expert Solution
Step 1

c).Given:        3x+4y=24-x+y=-1}⇒y=24-3x4y=-1+x}now equate value of y from above:   y=24-3x4=-1+x⇒24-3x=-4+4x⇒7x=28⇒x=4now put x=4 in y=-1+x⇒-1+4=3⇒y=3
