Question
Calculate the solution to these simultaneous equations using the substitution method: (1)(1)4𝑚+3𝑛4m+3n==3232 (2)(2)𝑚m==𝑛+1n+1
Solution
Sure, let's solve these equations step by step:
-
We have two equations here:
Equation 1: 4m + 3n = 32 Equation 2: m = n + 1
-
We can substitute Equation 2 into Equation 1. Wherever we see 'm' in Equation 1, we can replace it with 'n+1' (from Equation 2).
So, Equation 1 becomes: 4(n + 1) + 3n = 32
-
Simplify the equation:
4n + 4 + 3n = 32 7n + 4 = 32
-
Subtract 4 from both sides to isolate the term with 'n':
7n = 32 - 4 7n = 28
-
Divide both sides by 7 to solve for 'n':
n = 28 / 7 n = 4
-
Now that we have the value for 'n', we can substitute it back into Equation 2 to find the value for 'm':
m = n + 1 m = 4 + 1 m = 5
So, the solution to the simultaneous equations is m = 5 and n = 4.
