If this is a simultaneous equation then:
you should simplify it to get 18+2x=-8x+42+18x
Then simplify again and you get: 18+2x=10x+42
Next if you minus 2x from both sides you get: 18=8x+42
After that you minus 42 from both sides to get: -24=8x
Finally, divide both sides by 8 and you get: -3=x

Answer:

0.324m^2 ; 18 ft

Step-by-step explanation:

Given the triangle :

Base (b) of triangle = 54cm

Height (h) of triangle = 1.2m

Area(A) of a triangle is given by:

0.5 * base * height

Base = 54cm = 54/100 = 0.54 m

Therefore,

A = 0.5 * 0.54m * 1.2m

A = 0.324m^2

2.) Average of the two bases in the trapezoid :

From the trapezium Given :

Base 1 = 15 feets

Base 2 = 7 yards

1 yard = 3 Feets

Therefore, base 2 in Feets = 7 * 3 = 21 Feets

Average of the two bases :

(21 Feets + 15 Feets) / 2

= 36 Feets / 2

= 18 Feets
