Ineed with the equation i know what the value of x is . also their is only one equation .

40+90=130
180-130=50
50+130=180
x=130
50+x=180

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

Hey mate where is the graph
