The net effect of increase in government purchases and taxes both by $100 billion, the equilibrium real GDP will rise.
Explanation
we can understand the net effect of increase in government purchases and taxes by comparing the size of change in income due to tax multiplier and government expenditure multiplier.
In order to under the net effect of these changes on equilibrium real GDP, consider following example:
For e.g
MPC (Marginal propensity to consume) = 0.75 , MTR (marginal tax rate) = 0.25 and
Change in government purchases = Change in taxes = $100 billion
Government expenditure multiplier
Tax multiplier
Therefore, the net effect of these changes on equilibrium real GDP is $58 billion
