What is linear equation ?

In the algebraic form y=mx+b, where m denotes the slope and b the y-intercept, a linear equation is defined as a first-order (linear) term plus a constant. When x and y are the variables, the previous statement is occasionally referred to as a "linear equation of two variables."

Calculation

5.7 grams -------> one quarter

2.3 grams -------> one dimes

5.7 q + 2.3 d = 141.7

given q = 18

5.7 * 18 + 2.3 d = 141 .7

2.3d = 141.7 - 102.6

2.3 d = 39.1

d = 39.1 / 2.3

d = 17

therefore , no. of dimes in the bag will be = 17
