first you do 2x3 then divided by 2 to get one of the small triangles which is 6/3= 2 then double that to get the other small triangle so you have 2+2=4 then you find the area of the rectangle which you do 8+3 to get the whole of the length so it’s then 11x4= 44 then add the 4 from the two triangles and you get the area as 48 i think this is right
X+y = 4, therefore y = 4-x when you rearrange the equation. You can subsitute this in: x-(4-x) = 6 -4+x = 6-x x=10-x 2x = 10 x = 5 Substitute x into the previous equation: 5+y = 4 y = 4-5 y = -1
