1.) You add 18 to both sides          2.) You add 10 to both sides
    y = 6x - 18                                         y = 4x - 10
+18        +18                                      +10        +10
then you divide by 6                       then you divide by 4   
18 = 6x                                           10 = 4x
/6     /6                                             /4    /4
where x is equal to 3                      where x is equal to 2.5
x = 3                                                x = 2.5

Gekata [30.6K]

Answer:

base = 15 units

Step-by-step explanation:

We are given area of a triangle = 52.5 sq. units

Height is given as 7 and we have to find the base.

Using formula for area of triangle:

Area of triangle = \frac{base*height}{2}

52.5 = \frac{base*height}{2}

52.5 = \frac{base*7}{2}

52.5 * 2 = base × 7

105 = base × 7

base = 15
