Two-step equations. Solve X

4(x+3)=-24

first, distribute 4 to (x+3)

4x+12=-24

second, combine like terms

transpose 12 on the other side

take note that when transposing, the sign will change

4x=-24 + -12

third, add the constants

4x=-36 (when adding or subtracting two integers with same signs, their signs will remain)

fourth, divide them both by 4

since we are looking for the x

4x/4=-36/4

last, cancel the 4s on the left side

take note that when multiplying or dividing integers with different signs, their signs will be negative

x=-9

final x = -9

hope this helps!

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
