8x-2y=-6

-20x+5y=15

X=(-6+2y)/8

-20((-6+2y)/8)+5y=15

(120-40y)/8+5y=15

15-20y+5y=15

-15y=0

y=0

X=(-6+2 x 0)/8

X=-½

Lady bird [3.3K]

Answer:

40 cm

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

$\frac{4x}{x}$ = $\frac{48}{x+2}$ , simplifying gives

4 = $\frac{48}{x+2}$

Multiply both sides by (x + 2)

4(x + 2) = 48 ( divide both sides by 4 )

x + 2 = 12 ( subtract 2 from both sides )

x = 10

Hence

width = 4x = 4 × 10 = 40
