Answer:
Step-by-step explanation:
Given the formula for calculating the displacement of a body as shown below;
d = displacement
v = final velocity
a = acceleration
t = time
To make the acceleration a the subject of the formula, the followin steps must be taken;
Step 1: Subtract vt from both sides of the equation
Step 2: Divide both sides by t²

Answer:
Step-by-step explanation:
Solving by elimination and substitution:
x
+
y
=
7
x
−
y
=
−
3
on adding the two equations
y gets cancelled
x
+
y
=
7
x
