Answers
To get the result we have to find 120% of 40 and add it to normal sells. so 120% of 40 = 1.2*40=48 Now I can add 120% of 40 to normal sells 48+40=88 - its our result
How do I solve 2x-3y=-1 and y=x-1 with substitution?
Answers
2x-3y= -1 (label 1) y=x-1 (label 2) sub 2 in 1 2x-3(x-1)= -1 2x-3x+3= -1 -x+3= -1 -x=-4 x=4 sub x=4 into 2 y=4-1 y=3
therefore x=4 and y=3
